Hi Guys. On using the VW app with the little dongle that plugs into the OBD port - (yes, I know nearly all on here think it's a hateful device and refuse to use it), but I find it reasonably useful to track mileage etc.
Anyway, I don't want this to degenerate into a discussion about the VW dongle and app. I have a question re the reported battery voltage in the car. My GTI as you may know is only about 2 months old, but in that time, I've very rarely seen my battery voltage from the app go over 12V (most was about 12.2 volts). Currently according to the app, it's say at 11.7 volts. Does that sound right, as I seem to recall on my GTD (albeit with most probably a beefier battery) was always up in the high 12V low 13V's (using the same app). My journey to work is though a town with lots of SS traffic, but going home I've at least 9 miles of reasonably fast motorway then 3 miles of 50mph road.
Should I be worried or is there a way to definitively check this ? Is it as simple as a multi meter across the battery terminals ?
**edit**
I've just borrowed an accurate digital multi-meter from work and measured across the terminals, the voltage was actually 12.43 V. That sounds a bit more like it and it seems therefore that the voltage displayed by the app isn't all that accurate ?
